Panduit's PanelMax DIN Rail Wiring Duct positions DIN rail and components above an integrated wire management channel, providing up to a 30% smaller footprint than conventional wiring duct panel layouts. It is compatible with standard DIN rail and many DIN mount components, and its hinged, flexible covers ensure panel integrity while allowing access to the wiring channel. The product comes in three sizes and includes bases, covers, and fasteners to install user-supplied DIN rail. Optional accessories like corner strips and wire retainers are also available.

PanelMax™
DIN Rail Wiring Duct is an innovative wire
management solution that maximizes space utilization
within industrial enclosures for flexibility in panel layout
and reduced material and installation costs. The unique
design raises components from the panel surface for
easier access and faster terminations. DIN rail wiring
duct is compatible with common DIN rail and DIN mount
components1
to satisfy a wide range of applications.
The Industrial Automation Solution from Panduit meets
the most demanding requirements and applications with
a broad range of product systems that aid in reducing
design and assembly time, creating valuable panel space
savings, providing easier installation and maintenance,
and improving reliability.
